At first, when I got here, I was wondering how I can survive
without the Durian Season and Mangosteen Season

Now, still hankering after durians and mangosteens
But nevermind, I'll be home in less than 2 months'!
Cannot wait to eat! 
Ok.. how to survive the 4 seasons...
Summer
Like the slogan we have here "Slip, Slop, Slap!" aka slip on your
sunnies (preferably with UVA & UVB protection), slop on some
sunscreen, and slap on a hat!
Autumn
Now's the time to start wearing warm, fluffy bed socks esp. when
the nights start to get a lil' bit chilly. Good time to also start
looking around for long john's/thermal underwear!
Winter
A good coat is a must... looks good & keeps you warm, too! It
may rain some days, so be prepared with an umbrella! (hmm actually,
it will rain regardless of what season it is in Melb, I heard!
) It can get pretty cold in Melb, according to some
relatives living there, but if things get too dreary for you, sit
by the heater with a cuppa soup and a good ol' book, and you'll be
right! 
Spring
Ooh, my fave season of the year!
Beware the pollen, though. Some people get
really bad hayfever during Sept/Oct
If you do, try not to wash/hang out your clothes during days where
pollen count is high. Flowers will be blooming during this
season... take a trip to Canberra for the Tulip Festival!
